2004 Chevy Problem with the "Clunck" noise

Steering clunck noise when driving slow and turning the steering wheel. Just had to post the fix for this problem. Since I am new, it may be an old fix, but bear with me if so. This thing was driving me nuts. Clunck, clunck everytime you turned the wheel. Of course everybody I took it to said, it won't wreck you, it is safe. Drilled and tapped a grease fitting just above the main bolt connecting top to bottom and filled it with grease. Drove 10-15 miles and it is gone. Yes gone. Anyone need specifics, e-mail and I will pass along.
